Five manufacturing process innovations of Sichuan Danchi Automobile Parts Co., Ltd. have recently been granted patents by the state, marking proactive progress in the commercialization of indigenous innovation of core technology and the patented gear manufacturing process.
In recent years, in response to the upgrading of home-grown auto brands and the intensifying competition in the auto parts industry, Sichuan Danchi Automobile Parts has concentrated its resources, overcome difficulties, actively made indigenous innovation of technology and manufacturing process, established and improved institutions to encourage R&D and promote the commercialization of research results, and facilitated the development of new products, the fostering and commercialization of core technology and special process for gear parts manufacturing, to build up the company’s soft power for sustainable development. The newly developed crankshaft ring gear for 1.6L auto engines has thin wall and a big inner hole whose shape might change remarkably while the gear is processed. To address the technical difficulty, designers have made repeated experiments and successfully designed and produced the anti-deforming pneumatic clamping fixture for thin-wall ring gear, which considerably improves the processing precision and efficiency of parts and won the utility model patent from the state. At the spiral bevel gear production line, technicians carefully studied each part of the process and independently developed a cleaning device for surface grind sands after gear lapping, which won the national invention patent, to make gear lapping process more reliable for the rear-axle main reduction gear for minicars
So far, the company has won 29 national patents for its indigenous innovations of the manufacturing process, including four invention patents and 25 utility model patents, a strong support for the company's sustainable development.
